Shoulder Arthritis: Understanding the Pain, Causes, and Treatment Options 

Your shoulder is one of the most mobile joints in the body—and because of that, it’s also one of the most vulnerable to wear and tear over time. The shoulder is made up of three bones: the humerus (upper arm), scapula (shoulder blade), and clavicle (collarbone), all held together by a complex network of muscles, tendons, and ligaments. With nearly 360 degrees of motion, every part of this system needs to work in sync to keep your shoulder moving smoothly. 

When arthritis develops, that smooth motion can turn into pain, stiffness, and frustration. 

What Is Shoulder Arthritis? 

Arthritis simply means inflammation in a joint—and in the shoulder, that inflammation can affect one or more areas, leading to a decrease in mobility and quality of life. According to the CDC, more than 53 million Americans suffer from arthritis, and the shoulder is a common location for it to show up. 

Common Signs and Symptoms 

If you’re dealing with shoulder arthritis, you may experience: 

• Pain: 
  The most common complaint. Pain may worsen with activity and can even disrupt your sleep. 
• Stiffness or Limited Range of Motion: 
  Inflammation can make the shoulder feel tight or restricted. Some people also notice grinding, popping, or clicking sounds when lifting or rotating the arm. 

Types of Shoulder Arthritis 

There are several different types of arthritis that can affect the shoulder. Each one has a different cause and treatment approach. 

Osteoarthritis (Degenerative Joint Disease) 

This is the most common type, especially in adults over 50. It’s caused by everyday wear and tear. Over time, the cartilage that cushions the bones breaks down, causing pain, swelling, and stiffness. 

Rheumatoid Arthritis (RA) 

RA is an autoimmune condition where the body’s immune system attacks healthy joint tissue. It can affect both shoulders and lead to chronic pain, swelling, and permanent joint damage if not managed properly. 

Post-Traumatic Arthritis 

This type occurs after an injury—such as a shoulder dislocation, fracture, or severe sprain. Even years after healing, the joint may become arthritic due to lingering damage. 

Rotator Cuff Tear Arthropathy 

If you’ve had a significant or untreated rotator cuff tear, the shoulder joint may become unstable. Without support from the rotator cuff, bones can rub together, eventually leading to arthritis and reduced shoulder function. 

Avascular Necrosis (AVN) 

AVN happens when blood supply to the humeral head is disrupted, causing bone tissue to die and break down. Common causes include steroid use, heavy alcohol use, trauma, or certain medical conditions like sickle cell disease. AVN can lead to joint collapse and severe arthritis.
